To all whom/imag concern:

Be it known that I, ABEL RAIMOND ALEX- ANDRE GRARD DE RncoNDo, a citizenof the Republic of France, and resident of Faris, France, have inventednew and useful linprovements in Apparatus Enabling the Speed ofMotor-Cars to be Regulated and the Excess of Speed Recorded, whichimprovements are fully set forth in the iiollowing specification.

rllhe invention relates to speed indicating and controlling devices, andhas vfor its object to provide means Jror indic-ating1 the enrn rentspeed of a moving vehicle, limitingx the speedto a predetermined rate,and indicating the total distance traveled. For these purposes theinvention comprises an odometer.,l a speedometer connected therewith,which may be of the centrifugal governor type, tripping-mechanismconnected with the speedometer and adapted 'to operate when the latterarrives at a predetermined point, foei-controlling devices connectedwith 'said tripping-mechanism, and means connected with.theuel-controlling devicesy for recording and 4tor limiting the possiblenumber of infractions of the predetermined speedD rlheinvention-consists further of certain features of construction andcomhinations 'of parts which will be ,fully described here l inafter andfinally claimed.

- Simiiar reference-numerals indicate corresponding parts in the severalfigures of the drawings.

in the embodiment of the invention shown inthe drawings,tlie speedometerand odo1neter are located on a base 302 secured to any desired part 300of the vehicle. Fuel cut.- ot valves are employed, mounted on the sainepart er another part 301 of the vehicle. Said valves are adapted to bereleased for closing, and are normally held open by a.tripping-mechanism including a powertransnriitting;` device comprisinga idenible and inextensible steel wire 12 within a flexible and,incompressible conduitl, which conduit may consist ci' a closely-coiledwire helix. @n the base 302 is arranged a bed 10, and above the same afoot-plate 35 ig. 8) on which is supported by posts 37 a topplate 36. A.drive-eiwit 14ris mounted vertically in said toot and top plates and isconnected in any suitable manner with a moving part or themotor-vehicle, for example the hub ci" a wheei, so as to be driven at aspeed.

proportionate to that of the vehicle. Such means ot connection are wellknown and form no part of the invention and are therefore not describedin detail.

The odometer comprises a dial-plate 15 and a base-plate 16 connectedtherewith by posts 17. Between said plates is arranged a train ofcountengearing 18 having any desired number of arbore, withcorresponding dials and pointers 19, 20, 21, 22, 23.. The primary arbor24 carries below plate 16 a star-wheel 25, which is actuated onetooth ateach revolution of a pin 26 on a disk; 27' carried by a hub 29 on avertical shaft 28 fined at its upper end in a bracket 30 of the `iramey,of the apparatus. Below the disk 27 the hub 29 carries a gear 31 whichis driven by a pinion 32 on drive-shaft 14. A pawl 33 bears.

against the star-wheel and its wedge-shaped nose 34 and gives thestar-wheel at each movement a forward impulse from the position in whichit is left by pin 26, se that the next tooth or` the wheel is brought`in position to .ce engaged by the pin on eine followingl rotation ofthe disk 27 and heid in such position. y

The drive-shai't 1d carries a gear 38 for operating the speedometer. Sigeantrain 39, 40, 41, 42, is mounted between the plates 35 and 36 .and abracket 73 and transmits motion at increased s eed from gear 38` to apinion 43 secured to s aft 44 of a speed-sem sitive device of thegovernor type. Said device comprises jointed arms 45, 46, pivoted attheir lower ends to a head 47 fixed to shaft 44, and at their up er endsto a head 48 which is slidable on t e shaft. The ,arms are provided attheir middle joints withweights 50, 51. When the rod 44 is rotated, theweights move outwardly under centrifugal force and depress the slidinupper head 48 against a spring 52 on sha of downward movement of saidupper head being dependent on the centrifugal force,

which is itself dependent on the speed of rotation. vThe extent ofdepression of the head 48 thereby affords a measure of speed of theshaft and through the same of the vehicle. When speed isv reduced, theforce is diminished and spring 52 lifts head 48. The head is limited -inupward movement by abutment with a bracket 53 which supports shaft 44 atits upper end. By such abutment, friction. is caused between the headand bracket which assists in bringing the mechanism to rest.Limitationof upward movement of the head at this point prevents theweights, which project from the arms inwardlytoward the spring 52 andwould otherwisebear against the same, from contacting therewith.

Head 48 is provided above the pivots of the arms 45, 46, with an annulargroove 54, in which is received the ball-shaped end 55 of one arm56 of alever pivoted to a standard 59. of the frame', the other arm 57 of whichterminatesY in a toothed segment 58 which yengages a pinion 60 on anarbor 61 supported at one end in standard 59 and at the other `end in astandard 62 secured to a late 63 supported on posts 64. rising fromllied 10. To the arbor 61i's secured a pinion 65 which engagesdownwardly-proiectin teeth 66 at the rear-portion of a rac sai rackhaving at its forward portion laterallyprojecting teeth 67. The rack isguided 1n a housing' 68 secured to a standard 69 rising Vffromacross-bar 193 on plate 63, and at its rear portion is guided by aguide-roller 70 supported on a standard 71, said roller bearing at itsperiphery on the top of the rack and thereby retaining teeth 66 inengage-y ment with pinions 60, and having a circumferential vflange 72engaging the rack and reventing lateral displacement of the same 1n onedirectionwhile lateral displacement in the other direction is preventedby standard 7 1. Teeth 67 /engage a pinion 74 on an arbor 75 Vjurnaledin standard 69 and carrying at its upper end a pointer 76 movable over adial 77 supported on posts 78 rising from plate 63. A spiral spring 79is secured to shaft 75 and adiustably to standard 69 44, the extentwhich bears the flexible tube 13.

-by means of a post and peg 80, and serves to ,the governor mechanismand the pointer.

The latter thereby follows the movements of the former and by itsposition over the figures of the dial 77 indicates the current speed ofthe vehicle.

The valves may be loca/ted between the liquid-fuel tank and thecarbureter, or between the carbureter and the motor of the vehicle. Ineither case, they operate to close the fuel-supply when they aretripped. The valve-mec anism comprises superposed plates 82, 83,supported by posts 84 on a base-plate 81, secured to the vehicle. Avalve-housin 86 is mounted on the baseplate 81, an from the same extendtubular threaded heads 8 7, 88, adapted to be connected in the fuel-pipeof the vehicle, and

through which heads the fuel enters and leaves the housing 86. Thevalves 89, 90, are provided in the housing with the usual valve-plugs,and above the housing 4with spring-barrels 91, 92, respectively,containing each a spiral spring actuating the valve in closingdlrection, the spring 85 being secured at its inner endto a stationarypost 93 depending from the plate 83 within the secured to a similar post95 epending within the barrel 92. The barrels 91 and 92 are providedwith top-plates 114 and 115, respectively, located in openings in theplate 82 and bearin at their peripheries a ainst the plate, which platesare Hush wit the uppenface of the late 82. The top-plate of the barrel91 over angs the barrel and provides a flange 108 beyond the same. Tothe barrel 91 is pivoted a yoke 96, having a radially-projecting finger97 which is engaged by an arcuate cross-head 98 vertically movable onthe posts 84 and having a removable strap 99 adapted to retain thefinger 97 in engagement with the, top of the crosshead. A lever 100 ispivoted to standard 101 of the base-plate 81, and is connected at itsupper end with an adjusting device comprising a connecting-rod 49 havinga thread-A ed end en aged by a socket 102 swiveled on the end o wire 12.The socket is guided in a' tubular head 103 secured to plate 82 and toan end-plate 130. Head 103 is threaded at its4 outer end to receive acap 104, a ainst t its lower end lever 100 is provided withinwardly-curved feet 73 en aging the crosshead andada ted to lift t esame when the lever is move by a pull on wire 12.

To the pivot 105 of one arm of yoke 96 is pivoted a awl 106, located ina recess in the arm an extending at its tooth 1.07 through an opening inthe flange 108 of the valve. A spring 109 retains the pawl raised in theyoke. The length of the tooth 107 .spring-barrel 91, and the s ring 94being 95 is such that when the yoke is in lower position fshown inFig.14 the tooth does not project above the surface of the flange. A-valve-operating handle 110 is removably secured by nut 1,11 to thesquared upper end of a post 112, the lower end of which is fixed in aswinging lever-arm 113 ivoted to post 93 and movable over the 4sur aceof plate 82 and top-plate 114 of the first valve, and adapted to engagethe tooth 107 when raised above the ange 108, -and thereby move thevalve against the tension of its spring 85 from closed to open position.For retaining the lever-arm in'forward position a checkpawl.116 isemployed, which is pivoted at 117 to av block 118 attached to the underside of plate 82. The tooth ofthe pawl projects through an opening inplate 82 and is retained normally projecting above the same as indicatedin Fig. 14 by a spring 119. When arm 113 .is moved to forward position(Fig. 12) the pawl 116 engages behind the arm and retains it there. Forreleasing the arm and handle, a releasing-rod 120 is provided, which is'supported at its lower end on a lug 121 and extends vertically in plates82, 83 and is provided at its upper end with a detachable button 122.Spring 119 holds the rod 120 normally raised. A collar 123 xed on therod 120 between the plates 82 and 83 limits vertical movement of therod, thus preventing on the one hand depressing of-the same to so greatan extent as to strain the pawl spring 119, and on the other handpreventing accidental removal of the rod from operating position.

The second valve is provided with a lever 124 secured tol the top-plate115 and projecting beyond the same at one end into engagement with astopscrew 125 secured in plate 82, and havingthe other end 126 camshapedand in engagement with a motiontransmitting tapering wiper-lever 127pivoted to the plate 82 and limited in its movement away from the end126` .by an abut' ment 128 on plate 82, which thereby also serves as anabutment limiting further return movement of lever 124 and the secondvalve. Arm '113 carries a forwardly-extending curved lug ornose 129,which is adapted to engage lever 127 and press the same against cam-126, thereby operating the valve from closed position shown in Fig. 11to open'position. shown in Fig. 12, in which vopen position it isretained so long as the arm is retained by pawl 116 in forward position.When the arm is released, sprin 94 returns thevalve'to closed positionan lever 124 and wiper 127 to position shown in Fig. 11. The wiperassists in starting the valve, by its leverage over cam-'face 126 asshownV in Fig. 11. During operation it divides the friction and thusreduces wear on the parts.

A segment 131 is pivoted to post 93 be: tween plates 82 and 83, and isprovided at its outer. edge with a series of ratchet-teeth 132 and atits upper face with an indicatingplate 133 having numbers correspondingto the teeth. Posts 181 support the plate 133 inthe segment. The segmentis actuated by a spring134 coiled around a collar 135 on post 93 aboveplate 83, and secured at one end to the segment and at the other end tothe plate. The segment is limited in forward movement by abutment of one4of the posts 181 with plate 83, and in return movement b`y a stop-screw182 on the 'segment abutting against said plate. A cam-lever 136 ispivoted to plate 82 and extends at its cam-surface above plate 83. Atits o-pposite end it is pivoted-by means of a link 137 to a driving-pawl138 which is provided with a longitudinal slot 139 through which passesa screw securing the pawl to plate 82. Link 137 is pivoted to the pawlat a point behind the slot. To link 137 is attached one end of atension-spring 140, the other end of which is secured to plate 82. Acurved arm 141 is attached to post 112 and extends above plate 83 inposition to engage by means of its orward' end the cam-face of lever136, when handle 110 is moved for opening the valves. By this operationcam-lever' 136 is moved fromthe position shown in Fig. 11 to that shownin Fig. 12, and pawl 138 is thereby lmoved forward, advancing thesegment one spring 143, retains the segment in advanced position againsttension of its return-spring 134. When handle 110 is returned, carryingarm 141 away fromfthe lever 136, spring 140 returns the lever, link andpawl 138 into retracted position, ready when the arm 141 is againadvanced to again move the segment for a distance of one tooth. The noseof pawl 138 is forked and is adapted to engage in the fork the rearmosttooth 144 of the segment. When the segment has been by repeatedactuations brought to fully advanced position, on the return movement ofthe pawl its nose passes oil the last tooth. Spring 140 by its pull onlink 137, causes the link to assume a position whereby pawl 138 is nowdirected so that upon its next actuation it will engage-with its fork145 the rearmost tooth of the segment. If it be now attempted to operatehandle 110, the same will be arrested after a short movement by abutmentof arm 141 al i ainst `lever 136, which is retained in inter eringposition byengagement of the nose of the pawl with therear tooth 144,and abutment of the forward post of the segment against plate 83. Thesegment may be returned to original position by releasing the pawls`from the teeth. This is accomplished by a releasemember 147 pivoted topawl 142 and coni136 so as not to interfere therewith.

nected by slot and screw with pawl 138, and provided with anintermediate detachable operating handle 148. When this member is pulledin outward direction, both pawls are moved out of engagement with thesegment, and spring 134 returns the segment intol original vpositionready for rengagement.

For preventing opening the second valve unless the parts be first placedin position for operating also the first valve, a stop-pin 151 isprovided, vertically movablein plate 82 and in a guide-tube 152extending below the same, said pin projecting abovethe plate 82 andbeing movable into and out of the path of nose 129. The pin is supportedby a lever 153 of spring-wire, which is attached to plate 82 and extendsthrough an eye in the lower end of pin 151 and beyond the same is bentupward and then downward (Fig. 14) and curved approximately concentricwith the first valve (Fig. 13) until. its forward end extends beneath afinger 155 projecting radially from and rotatable with the first valve.When said valve is moved, the finger 155 rides upon the curved portion154 and depresses the same, drawing pin 151 ldown so that its upper endis below path of nose 129. After finger 155 passes the camportion154,*pin 151 is retained depressed by l abutment at its upper endagainst bottom of nose 129. l/Vhen the nose is returned, the pin againrises into position.

An indicato-r 157 is pivot/ed to post 93 between plate 83 and collar135, and swings in a horizontal plane above arm 141 and levler T eindicator is provided at its outer end with a portion 158 colored red,and an adjacent portion 159 colored white. A slot 16() in theindicator-plate 157, and screw 161 in the same and secured in plate 83,guide the indicator and limit its motion.

A casing 162 covers the valve-mechanism described, and is secured toplate 81 by screws (not shown) passing upwardly kthrough said plate intothe casing. For

placing the casing in position, handle, 110, button 122, and handle 148,are removed. The case is then lowered over the mechanism. Heads 87 88and 103 enter recesses extending upwardly from the lower edge of thecasing. Pest 112 projects through an arcuate slot 165 inthe casing top.Pin 120 projects `through an. opening in the top of vthe casing. Ascrew-threaded stud 166 of the release-member 147 is located opposite anopening in the side-wall of the case, said opening being of such 'sizethat the handle v 148 may be inserted through the same and screwed uponthe stud.l The casing is provided in its top with a sight opening 168 insuch position asto expose to view the cipher of the indicator-plate 133when the segment 131 carrying said plate is in initial position,

and the other figures in succession, one at a time, when the indicatoris moved. The casing is also provided in its top witlra sightopening 169to expose to view the red portion 158 of indicator 157, when the latteris in its position shown in Fig. 11 to which it is normally returned andretained by its spring 170, and to expose to view the White portiononly, when the indicator is in forward position to which it is moved onrotation of the first valve by means of a stud 171 projecting upwardlyfrom the top of the valve and engaging a lug 172 projecting downwardlyfrom the indicator-plate 157. The indicator 133 thereby forms a recordershowing, at any time, the number of times the valves have been opened.The indicator 157 does not move from red to white until the parts havebeen so far advanced as to open not only the first but also the secondvalve. 1t therefore indicates at any time whether the valves are open,by showing white, or closed, by showing red.

The parts being in initial position (Fig. 1.1), for opening the valveswire 12 is dra-Wn outwardly, which causes rise of cross-head 98 againstthe action of springs 173 secured upon plate 81 and bearing downwardlyon studs 174 one at each side of the crosshead. Finger 97 is therebyraised, bringing tooth 107 above the top of the first valve. Wire 12 isretained taut, thus retaining the parts lifted. Handle 11() is movedforward, whereby arm 113 engages pawl-tooth 107, thereby rotat-ingthefirst valve. Finger 97 bears upon lever 153 at 154, lowering pin 151 ontof path of nose 129. Arm 141 engage's lever 136, causing pawl 138toadvance segment 131 one tooth and show lfigure 1 in sight-opening 138.Nose 129 engages 'wiper 12 which swings cam-lever 124 and opens thesecond valve. Simultaneously stud 171 engages lug 172 of indicator 157and moves the same so as to show white 159 at sightopening 169. Arm, 113passes beyond pawl 116 and is engaged thereby and prevented fromreturning, thus holding first andv second valves open. Fuel is now freeto pass through the valves and heads 87, 88, and thence tothe'carbureter or motor.

When from any cause wire 12 is permitted to relax, cro-head 98 is deressed by its springs 173, brin ing down nger 97, thus withdrawing toot107 from arm 113. The first valve is immediately returned by its spring85 to closed position. During this return, pin 171 passes by way of arecess I17 8 in arm 113, to opposite side of the arm,

thus releasin indicator 157 and ermitting the-same to e moved by itsspring 170 in return directie-1n The indicator abuts against the forwardedge -of a plate 180 .upon arm 141 in position showing red,

thereby indicating that the valve is closed. Plate 180 is preferablyextended at the rear- Qfide of post 112, forming there a blind,l

which constantly closes slot 165. The indicator is stopped b v plate 180slightly in advance of abutment with the screw 161, and thereby thehannncring due to repeated returns of the indicator is taken off thescrew and rweived by the plate, which is provided with a broad end toreceive the blow without injury. Button 122 is depressed, causing` pawl116 to descend out of path of arm 113. which may now be moved in returndirection to initial position, thus releasing wiper-lever 127 and valve90, which is returned by its spring 94 to closed position. A rin 136 andpawl 138 are returned by spring 140. Indicator' 157 comes to restagainst limiting screw 161.

Repeated operations of opening and closing the valves- 89, 90 andindicating the number of times opened may be thus accomplished until thelast tooth 144 of the segment is reached, when the parts are arrested asbefore described. In this advanced position, lever 136 stands in thepathof arm 14.1 and prevents advance of the same and of post 112 andattached parts to the point of opening .of the valves. Foropening thevalves, handle 148 of the pawl release meml ber 147 is drawn outwardly,disengaging the pawls, segment. 131 returns under pressure of spring 134to initial position lwith stop screw 182 against plate 83 and the cipherof the scale at sight-opening 168. The opening and closing operationsmay now be repeated as before to the limit of the recorder, which mayhave any desired number of teeth in its segment 131, and correspondingfigures of the scale.

In case it be attemptedto open the valves without first drawing .taut'wire 12 and t-hus raising tooth 107, no operation of the valves takesplace, because arm 113 which is swung by handle 110 has no engagementwith the first valve, and nose 129 is arrested by pin 151 before it canarrive at wiper 127. A slight movement of pawl 138 is caused by arm 141engaging lever 136, but this movement is insuflicient to operate thesegment 131 for a distance of a tooth, and on returning handle 110 allparts resume their original position.

Handle 148 is provided with an openingin register with a like opening ina post 183 projecting from the casing, through which openings passes thebail of a detachable lock 184, which prevents release of the `segmentafter operation to capacity, and by retainingr the handle upon the stud166 prevents removal of the casing, whereby the mechanism is protectedagainst accident and tampering.

The tripping mechanism by which the wire 12 after having been draw-mtaut is relaxed, is controlled b v the speed of the vehicle throughdrive-shaft 14 and the speedometer gearing, governor and arbor 7 Atrigger-pin 185 extends radially fromr At one end the rack is connectedby a connecting-rod 196-with a cam-lever 197 pivo'ted above the rod 196to a standard 198 rising from bed 10. Below the rod 196 -lever 197 isprovided with a cam 199 tangential to the arc of the lever whereby thelever is adapted to be swung on its pivot 200 by a descending finger 201striking the cam transversely. A tension-spring 232 secured to the leverand to a bracket 203 of the standard, actuates the lever rearwardly,that is to say, in iinger-liftin'g direction of the cam. Then the fingeris lifted out of contact with the cam, return motion of the lever islimited by abutment of screws 195 with the ends of their slots 194. Whenarm 201 strikes the cam and moves the lever, rack 191 is moved, rotatingpinion 190 and fork 189 through part of a rotation, whereby trigger 186is correspondingly moved and the relation of its notch 187 to triggerpin185 changed, to greater or less distance than before from thetrigger-pin, thereby requiring movement of the pin through a longer orshorter arc before arriving at the notch.

Arm 201 is mounted rotatably on and eX- tends radially from a shaft 202and is actuated thereon toward cam 199 by a spring 205 coiled on theshaft and secured at one end to an adjustable collar 218 and at theother end to thearm or finger 201. An adjustable arm 204 is fixed byset-screw to the shaft and is adapted to engage finger 201 and lift itfrom the cam. Shaft 202 is journaled in bearings 206, 207 secured to bed10. and carries at one end a radiallyextending stattl 208 supporting at4its outer end a signal 269 preferably of metal or other stili' material,and of any suitable shape and color. At its opposite end shaft 202carries' a handle 210. Art one side of the shaft 202 is pivotcd in astandard 211 a signalindicator 212 of sector shape, the outer face ofsaid indicator at one side of a middle radins being colored red. and atthe other side white. Said indicator is operated by a piu 213 whichextends radially from a.

collar 214 secured on shaft -202 by a set screw. .lVhen the rod 202 isoperated in signal-raising direction as shown by the arrow in Fig. 7pin-213 engages an extension 216 of the indicator and lifts the same Lvl Oagainst tension of its spring 217. lVhen the shaft is returned, thespring returns the indicator to lowered position, with one edge abuttingagainst standard Q11, and retains it there until again operated.

@n ay post 219 rising 'from bed 1() is secured a dial Q20 provided withfigures indicating rates of speed. and with a recess 221- at each figurein which is adapted to be seated a button Q22 at the end of a handledpointer 223 secured to an arbor El at the center of the dial. stop Q25on the dial limit-s rotation ot tbe pointer in both directions. Handle223 is of spring-metal, and arbor has slight vertical play, whereby easydisengagement and movementy of the button trom one recess to anotherpermitted. and the button is caused to reliably7 engage in tbe recesses.At its lower end arbor Q2-1 is ]ournaled in bed 10 and carries above thesame. a pinion 226 engaging a gear Q27 by which motion of the pointer223 is transmitted to a rack 22S guided on tbe bed between guides 2:29thereon and a horizontal guide 9230 secured to post 219. (luide i'trretains the rack in the ways 229 and also serves to guide at one side anabutment 9531 integral with the rack 22S and provided at its upper edgeabove the rack with a plurality of steps coriespomling` to the number otrecesses or seats 221.

Abat-ment Q31 is located adiacentand parallel to cam-lever 19T. and inthe path ot linger 201, so thaty when the finger dcscends upon cam 199it contacts also with and is arrested b v abutment 231. The steps arearranged in order of height so that when pointer is at the lowest figureot the dial Q20 the highest step presented to linger Q01. Shaft 202.isinclined to bed 10. being higher-at standard 20T than at standard20o. and where it passes the abutment 231 it is amiroximately in theplane ot one ot the middle steps ot the same. so that under the averageconditions et speed. corresponding to said steps. linger 01 will beenabled to rest approximately llat and horizontal upon and therebyengage to the best advantage the cam 19S) and the step. The treads otsaid middle steps are made approximately horizontal to receive linger201. and the upper steps are laterally beveled as indicated in Fig. -l-.toward the linger, so as to permit good engagement of the fingertherewith. top-step shown as considerably above the plane of the top ofcam 199. when the abutment is advanced so that that step comes in thepath of the finger and the l; tter operated to rest on said step. thefinger by reason of its downward inclination from the step bears uponand imparts a limited Atorward movement to the cam. thereby cau-ing:ei-eens@ The lower steps of the abutment may be laterally beveled inopposite direction. The finger 201 being in raised position, pointer Q23is placed at any desired 'figure of the dial, whereby the correspondingstep is placed in the path of the finger, and the latter permitted acorresponding descent, the cam is correspondingly moved and the trigger186 accordingly set. The pointer may be moved from a lower to a higherligure of the dial without raising finger 201. Upon moving the pointer.abutment 231 is retracted beneath the linger and the latter descendsunder pressure of its spring 205 from step to step and at each descentactuates the cam for an additional distance, causing corresponding`advance ol trigger 186 and bringing the same to rest in a positioncorresponding to the speed at which the pointe is dropped.

Arbor is journaled at its lower end in the upper end of a post 2353.which is secured in plate 68 and passes through and is braced bycross-bar 193. Pinion 190 is mounted on post Q33 at the upper endthereof; and retained thereon by a clip 231 secured to the cross-bar. Topost Q33 is pivoted a latchplate Q35, and above the same. also pivotedto the post. is a latch-lever 2356, which carries at its outer end alsocket 23T adapted to receive the reduced inner end ot a detachableoperating handle ffl-. Said latch-lever also carries at itsr outer endan arcuate blind 2251. which bears` at its lower edge on bed 10 andthereby supports` and guides' tbe lever Q36 at its outer end. ,t curvedhorizontal bracket 2l() is secured to the plates (32%. 193. and carriesat its outer end a check-pawl Q-l-l projecting' downwardly from thebracket in the path of latch-lever 2536 and -adapted to engage andretai'n the same in advanced position.

hatch-plate Q35 extends lnn'iZontally from post 2323 and nipported andguided on plate G8. Beyond said plate'it is provided with a latchcon'iprising a pawl Q12 and a keeper 2l-f3 pivoted between a dependingportion :7l-1 of the latch-plate Q35 and an outer plate Q15 connectedtherewith by bolts Qld. two of which bolts torni pivots tor the pawl andkeeper. The keeper is provided with a leg Q-l-T extending downwardly andoutwardly beyond the edge ot latch-plate 2li and limited in inwardmovement by abut- Thus. notwithstanding in Fig. t thev correspondingmovement ot trigger 18h.'

ment with a lower inturned horizontal portion ot plate Q-l-i. Yhen inlsuch inward position a curved arm 2l-9 of the keeper retains in raisedposition a tlnger 230 of the pawl. and thereby retains the nose of thepawl in engaging position above plates Q44. 21j and in the path of apawl Q51 which is carried by and projects trom'the lower face otlatch-lever 23C in ('wuposite direction to pawl Pawl is actuated inengag` 1,ioc,254

ing direction by a spring 252 connected with a pin 253 extendingdownwardly from the pawl, and at its other end connected with plate 244,and is arrested in engaging position by abutment of the pin against oneof the bolts 246 which forms a stop, and also by abutment of finger250-with a nose 254 of the keeper, finger 250 being located between saidnose and curved arm 249.

A lever 255 is pivoted to bed 10 and ccn retracted condition and pawl107 of the rst valve depressed. Latch-lever 236 is capable of rearwardmovement to a point beyond pawl 242, so that pawl 251 is brought intoengaging position behind pawl 242 as indicated in dotted linesin Fig,10. Motion ci the latch-lever rearwardly is limited by abutment of thelever with bracket 246 (Fig. 3).

Trigger 186 is provided at its top with a hub having a flange 259 bywhich the triggerv is swiveled to a curved connecting-rod 260 which isguided in a -lork 261 secured to plate' 235 and pivot-ed at its lowerend to one arm of a crank 262,-the other arm of which 4is pivoted to alink 263 pivoted at its opposite end to the lower end ci a releaselever264 pivoted at its upper end to latchplate 244.y Crank 262 is supportedon plate 244 between brackets 265. Thus the parts mentioned, fromconnecting-rod 260 to release-lever 264, are all supported on latchplate235, 244, and are movable .with the same in an arc 'about post v233 as acenter. Bed 10 is provided-with an opening 266 ,(Fig, 5) for permittingswinging of the crank, link and lever 264. The latch-plate 244 carriesat its inner face a pawl comprising a pawl-lever 267 pivo-ted to swinghorizontally', and extending at the keeper-end of the latch-mechanismbeyond plate 244, and spring-actuated at its rear end into contact withrelease-lever 264. At its forward end lever 267 carries a swinging tooth268 which is actuated by a spring-269 on the lever into outward,engaging position, into the path of keeper-leg 247. lt is limited insuch position by abutment with the pawllever 267.

When-latch-arm 236 is moved by handle 238 from rearmost position inforward direction as indicated by arrow in 2, pawl 251 engages pawl 242,causing the latch"- mechanism to be carried along with the arm.

In this position, paWl-nger 250 is bearing down on keeper-arm 249, andthe leg 247 of the keeper is pressing outwardly against pawl-tooth 268,which is retained in engagement therewith by release-lever 264 actingagainst the rear end of pawl-lever 267 against the tension of spring270,'said release-lever 264 being held in suoli position by thelever-mechanism described and which is sustained by the trigger restingon triggerpin 185. The latch-arm is brought forward of checlr-pawl 241,which then retains al the parts in forward position. JV ire 12 has beenduring this movement drawn taut by abutment of the flexible helix 13 atone end against cap 104 and at the other end a ainst an adjustablenipple 271 screw-three ed in a socket 272 secured to bed 10.

rlrigger 186 and its pin 185 are so located that when a speed oi thevehicle in excess of that for which pointer 223 is set is attained, thetrigger-notch arrives at pin 185 and the pin enters therein and thetrigger falls, under the combined action of its weight and the weight ofconnecting-rod 260, and of the pressure of spring 270. The release-leveris thus permitted to swing back and pawl 267 to be moved by spring 270so as to withdraw tooth 268 from keeper-leg 247, which permits' thekeeper to swing on its pivot into position shown in dotted lines in Fig.10, in which position 249 no longer sustains pawi 242 in engagingposition with pawl 251, but by permitting finger 250 of the pawl todrop, permits the pawl to tilt backward under the continued pressureagainst pawl 251, until the angle between the engaging faces oit-liepawls is so reduced that both pawls yield against the pressure of theirsprings and pass out of engagement. The awls then at once resume theirerect positions. The latch-plate 235, 244 and attached parts continuetheir return movement under influence of spring 257'to rearmostposition., rllhe latchlever 236 and handle 238 remain in orwardposition.

During return motion of the latch-mechanism, trigger 186 is re-set by acam 274 secured at its higher end to latch-plate 235 and extending atthe rear of the same beneath a lifting-lever 275 pivoted at one end to,bracket 240 and at the other end engagiiig trigger 186 at its lower'edgeand lifting the same above the trigger-pin. By the lifting of thetrigger, release-'lever 264 is swung outwardly, Yre-set-ting pawl-tooth268 in the path o heeper-leg247. rlhe return motion of the parts undertension oia spring 257 is rapid, and should toothv 268 be replaced inthe path oi les 247 before the leg had itself descendethe two parte willengage, with 1 the leg extending downwardly at the outer tace 'orthe-tooth. The tooth yields against spring 262 and perinits'the leg topass-,into

place, and'then springs outwardly into position. For facilitating returnof the keeper, pawl-spring 2.52 is arranged to bear upwardly againstkeeper-arm 249 as shown in Fig. 10, in dotted lines.'

The lifting-lever 275 supports trigger 186 raised off pin 185 while thelatch-mechanism is in rear position. When the latch is moved forward asdescribed, cam 274 permits the lever to descend, thus allowing thetrigger to'rest upon its pin. Reliable return of the latch to initialposition is secured by abutI ment of the latch-lever 236 with the highrearend of cam 274 during return of the lever 236.

Over the odometer, speedometer and tripping-mechanism. is placed acasing 276. The flexible connection 12,13, may pass through said casingor through an aperture 277 in bed10. The case is at one part curved inan arc around post 233 as a "center, or approximately so, and in saidpart has a horizontal slot in register with socket 237, so thatthehandle 238 may be inserted therein and the latch moved. Blind 239 coverssaid slot at each side of the'socket, and is made of spring metal andcurved in van are slightly larger than the,

arc of the casing, as indicated in Fig. 6, so as to press against thecasing and exclude dust. At the top,'the casing has an opening 280 forthe odometer dial-plate 15,

and an opening 281 for the speedometer dial 77 both of which arepreferably closed by glass. An opening 282 is provided in the casing-topfor the dial 220 of the tripping-mechanism,which opening ispreferablyclosed by a cover 215 hinged to the casing-top at one s ide ofthe opening and provided with an arm 283 extending 'to the `side 'of thecasing and there secu-red to a lug 285 by a detachable lock`284. At oneside of the casing is an opening 286 for the indicator 212. The casingis secured at its lower edge by screws through a flange 287 to base 302.From its lower edge extend upwardly vertical slots adapted to receiveshaft 202 when the casing is placed in position. In the casing issupported a pushbutton comprising a tube 288 in which is guided apush-rod 289 adapted at its end below the tube to engage pawl 241 andmove the same in releasing direction, and spring-actuated in oppositedirection against a sleeve 290 in the up er end of the tube. The sleevereceives andp guides a removable thumb-piece 2924 adapted to depress thepush-rod. For ,f additionally securing the valve-casing in position,apost 298 extends from plate 83 and is provided above the casing with anopening receiving a lock 299.

Handle 210 having been turned so as to raise the` signal 209, wherebylinger 201 is raised from abutment 231, setting-pointer vto itssucceeding figure.

223 is now set at the figure of the dial indicating the speed wlhich itis desired that the vehicle shall not exceed. The handle 210 is nowreturned, depressing the signal 209 and causing finger 201 to set thetrigger 186. The recorder 133 having been set at zero in the mannerdescribed, and the locks 184, 284 and 299 having been secured,handle 238is advanced from initial position, thereby setting the latch and raisingtooth 107. Handle 110 is now advanced from initial position, therebyturning the valves and admitting fuel, and simultaneously advancing therecorder one figure, and causing indicator 157 to show white in thesight-opening 169. When the vehicle is in motion and drive-shaft 14operated, the odometer operates as a counter and indicates by theposition of its pointers the total distance traveled. The speedometerpointer swings constantly over its dial, indicating the varying speed ofthe vehicle. So long as the speed remains below that to which pointer223 is set, the valves remain open. If, however, it should be desiredfor any reason to close the valves, this may be done at any time bydepressing button 122, whereby pawl 116 is disengaged from valve-arm113. The valve-springs now close the valves, causingindicator 157 toshow red. Handle 110 is moved back to initial position owing tocontinued engagement therewith of pawl 107 of the first valve. Thevalves can now be reopened, andnin doing this the recorder is actuatedThe setting of pinter 223 to the speed desired has caused rotation oftrigger 186 so that its' notch 187 `is at that angular positionrelatively to the pin, 185, corresponding to the angular position of thefigure of the predetermined speed on the dial 77, relatively to thespeedometer pointer 76, with which thepin has similar movement. Thus,the predetermined speed having been reached, the pin 185 arrives at thenotch 187, the trigger falls and releases the latch, which recedes,permitting wire 12 to relax, tooth 107 to desoendyand the rst valve toclose. Fuel is thus shut off. For re-starting, thumb` piece 292 isdepressed, releasing handle 238, which is then moved rearwardly by handandagain moved forwardly, thus re-setting the latch and trigger. Button122 is depressed, permitting handle 110 to be moved ,rearwardly and thenagain forwardly, re-

opening the valves and advancing the recorder one figure, and settingthe indicator 157 at white. The allowed speed may be exceeded the numberof times permitted by the recorder. After the last time, the forked noseof pawl 138 engages segment 131 and prevents reopening of the valves, asdescribed. It then becomes necessary to releaseV lock v184 and, bydrawing handle 148,

abutment 231 is such as to lift t e finger 201 from the topmost step,which corresponds `with the slowest figured speed on the speedometerdial, after the signal 209 is raised above the casing, that is'to say,at-'a point when 'it approaches its fully raised position. 4 When finger201 is so completely raised from Vthe uppermost step, lever 197 is movedby its spring 232 an additional distance rearwardly before being stoppedby screws 195, thereby setting trigger 186 tol release at a point oflower speed than the lowest speed on the dial, and at any arbitrary lowspeed desired, being the lowest speed at which the speed-controllingdevice is adapted to operate, and which, instead of being indicated bythe pointer on the dial 220, 1s indicated by the presence of the signal,appearing above the casing. When this speed, for example, is the lowestlegal speed permitted within villages, the exposed visual signal 209indicates that the vehicle is traveling under a speed-controlledmechanism set to operate at such legal speed. The signal 209 issustained in elevated position by abutment of its staff 208'againstarest 293 secured to the base 302 and sustaining the same at one side ofthe center of avity, so

that the weight ofthe -overhanging siial y ise 209 retains the stati1against the rest. of signal 209 is .accompanied by a showing byindicator 212 of red in opening 280, and the lowering of said signal bya showlng of white. j

`Division ofthe device into two parts connected by flexiblepoweretransmttin means,

Venables the valve-mechanism and t e tripping-mechanism to beconveniently placed at separate parts of the vehicle, as, for example,the tripping-mechanism, odometer and speedometer at a point within thelvehicle within easy view and reach of the driver, but thevalve-mechanism at a point remote from his seat,so that it will benecessar for hlm to alight from the vehicle to open t e valves. Thenecessityl of getting out of the vehicle proves an additional deterrentagainst excessive speed.

The deviceenables for violations of spec the device is initially set byan authorize oiicial for a legal speed, and is then locked and the keysretained by him. After the limited number of infractions` have beenrecorded, it is necessary to the further use To accomplish this of thevehicle that the device be released by him, thus givin him anopportunity to assess such pena ties as are prescribed for theviolations recorded.

It is obvious that changes may be made in the construction wit-houtdeparting from the spirit of the invention.

I claim:

1. The combination of a speed-controlled mechanism, a fuel-valve-controlled by said mechanism, and means for locking 'said valve after apredetermined number of oper. ations ofthe same.

2. The combination of a speed-controlled mechanism, a fuel-valvecontrolled by said mechanism, means connectedwith said valve for-indicatin the same, an means for locking said valve after apredetermined number ofoperations of the same.

3. The combination of means controlling a source ofk power, aspeedometer, and a manually operable tripping mechanism between `saidspeedometer and controling means and adapted to retain said controlmeans in open osition.-

4. The comblnation of a speed-controlled mechanism, a fuel-valvespring-actuated in closing direction, a second fuel-valve independent ofthe first valve and also springactuated 4in closing direction, and meansconnectin said speed-controlled mechanism with the rst valve.
